Spruce Knob, Mid State Trail, Rothrock State Forest is a 3.4 mile out and back trail located near Alexandria, PA and is rated as difficult. The trail is primarily used for hiking and is accessible year-round.
We had issues finding the actual trail. The gps took us up a really cool dirt road and we wound up hiking what looked like old ATV trails. That being said the place we were was a pleasant drive and a nice hike. You can see where exactly we wound up as I recorded our journey using this app.
